Introduction to Omega-3 and DHA
Omega-3 and DHA are essential nutrients for the health of both mother and baby during pregnancy. DHA (Docosahexaenoic acid) is a type of omega-3 fatty acid that plays a crucial role in the development of the baby's brain and eyes.
The Role of DHA in Pregnancy
DHA supports the development of the baby's brain and eyes, as well as the development of the nervous system. Additionally, DHA may help reduce the risk of certain diseases, such as asthma and allergies, in newborns.
